Midnite Solar Rosie 7000W 48V Inverter/Charger

MidNite Solar logo

The Rosie 7048RE from MidNite Solar offers excellent versatility and incredible surge capacity. This high-frequency hybrid inverter/charger is ideal for medium-sized grid-tied solar energy systems with 48V battery storage with loads that demand high startup current surges like induction motors. Intelligent grid/generator connectivity features support peak load shaving, self-consumption and UPS based on battery bank setpoints of your choosing - allowing you unparalleled control over when and how much to draw from AC sources.

MidNite Rosie 7048 Inverter at a Glance

  • 7kW continuous power output
  • Best-in-class 20kW surge capacity
  • Three operation modes:
    • Grid/generator support - the Rosie will only draw grid/generator power when your batteries fall below your chosen SOC or voltage setpoint, or when loads exceed the breaker size on the AC input
    • DC voltage disconnect/reconnect - the Rosie will disconnect from the grid/generator when the battery voltage exceeds your disconnect setpoint, and then reconnect when it falls below your reconnect setpoint
    • Time of use - the Rosie will not use grid/generator power during "blackout" times of day you set to help you avoid peak utility rates
  • Selectable AC output:
    • 120/240 60Hz
    • 120 only auto-sensing
    • 230 50Hz
  • 48V battery charger with 120A power-factor-corrected battery charging current
    • Compatible with battery types including lithium, flooded/sealed lead acid, and more
  • 60A transfer relay per 120VAC leg
  • Zero transfer time - Rosie is always connected to your loads and the grid is paralleled into the system with a relay
  • 2x aux terminals (200mA at 12VDC) for automatic generator starting, diversion control, etc.
  • Streamlined CanBus communication:
    • One battery configuration menu for ALL midnite CanBus products in the system; components added later will automatically find and join your system config
    • Battery voltage sensing circuit shares voltage with all CanBus devices so all devices regulate to same voltage - coming soon via firmware update
  • Listed to UL1741, UL458, and CSA 107.01
  • Made in the USA

Note: The Rosie is ideally suited to pair with the Rosie E-Panel and Hawke’s Bay or Barcelona MPPT charge controllers. If using a MidNite Solar Classic Charge Controller with the Rosie, you will need a MidNite Solar Graphics Panel (MNGP2) for system configuration.
